[Petal] How do I use selected/checked ?

[Olaf Buwen]

This template:

<select>
    <option
	petal:repeat="entry options"
        petal:attributes="value entry/lang; selected entry/selected"
        petal:content="entry/title"/>
</select>

with this code:
...
print $template->process(
    options => [
        {lang => "foo", title => "Foobar"},
        {lang => "bar", title => "Barbar", selected => 'selected'},
        {lang => "baz", title => "Bazbar"},
    ]
);

gives this output:
<select>
        <option value="foo" >Foobar</option>
	<option value="bar" selected="selected">Barbar</option>
	<option value="baz" >Bazbar</option>
</select>


It is not in the docs, but AFAIK it is part of the TAL spec
that an attribute is not set when the appropriate entry is missing.

I hope this helps
